i just checked the backspacing on my police wheels and they are indeed 4.5 , if im doing it right. I put a straight edge across the back side of the rim and then measured down to the bolt face on the inside and it came out to 4.5"

does that mean i should be good to go with the above suggested tire sizes ?

moparpollock, I also have a set of 7 " wheels, would this change the tire size rec. or would you still go with the 225 70 15, the back spacing is also 4.5"



thanks.
